Notes: aFor shoot fresh weight, root fresh weight, root gall index Trial 2, and eggs per g of root Trial 1 with pepper, means within a column followed by the same letter are not significantly different according to Tukey’s adjustment for multiple comparisons (P ≤ 0.05). For root gall index Trial 1, total eggs per root system, and eggs per g of root Trial 1 without pepper and Trial 2 with and without pepper, means within a column followed by the same letter are not significantly different according to a Kruskal–Wallis test with a Wilcoxon test for each pair of multiple comparisons (P ≤ 0.05). Lower case letters are for comparisons among Festulolium plants only. Upper case letters are for comparison among all plants, including pepper; broot gall indices follow Daulton and Nusbaum (1961). 0 = no galls, 1 = 1 to 4 galls, 5 = 5 to 25 galls, 10 = 26 to 100 galls and 25 = more than 100 galls.
